I've been researching to make a pole style GoPro mount for my kayak for some time and being home has given me the access needed to tools and odd nuts, bolts and washers I needed to complete the creation. There are a number of options for creating something similar I got this design idea off the kayak tips, tricks and reviews site Unsponsored.
Firstly I acquired all the pieces I would need for the design and tools.
1x Cut down piece of steel
2x Bolts from original Fluid grab handle
1x Bolt and fitting Nut
1x Large Washer
2x 32mm End Cap Plug
1x Cut down piece of PVC pipe (not sure what diameter this was it was scrap i found in my garage). (55cm Long)
1x GoPro flat mount
1x Length of strong cord
1x Electric Drill
1x Metal Saw
1x Adjustable Spanner
1x Flathead Screw Driver
1x Allen Key set
I removed the original rear grab handle from my Fluid Detox
by unscrewing it and then used the original handle as a template for
the new one. I cut the odd piece of steel to the correct length then
drilled two holes for the handle to be re attached then a third hole in
the center of the handle. Thats that piece complete.
to complete the rest of the "base". Firstly drill a hole in ONE end
cap. You should then be able to use the 1x Bolt and Nut and 1x Large
Washer to construct it. I took into account I'm not always going to be
using the GoPro mount and therefore have tried to keep the handle and
base as snag free as possible so it can still be grabbed by someone in a
rescue situation or possibly be used to clip the boat if it needs
rescuing (hopefully will never happen!). To keep it snag free I
shortened the Bolt I was using so to not stick out above the End Cap.
